Places one block's samples onto the expected uniform sampling grid:
interpolates values for sub-period timing jitter and inserts NA rows at
longer-than-expected gaps (dropped samples).
Value
The block data frame placed on a uniform grid, with inserted (gap)
rows marked in a logical is_resampled column. Returned unchanged (with no
is_resampled column added) when no reconstruction is needed.
Details
This function is called by the exposed wrapper resample().
